I did my first brew class last month and had a really great time. We had 12 people...strangely enough 2 couples, and a family of 3 amongst the ranks. One of the wonen was a Chemical Engineer. Appaerently, I convinced her that her non-engineer husbad was right about the hobby: It is more about the process, the science and the experimentation than about getting drunk in your basement on your own crappy brew you made for 1/2 the price of buying decent beer.
I sent out a SurveyMonkey.com survey with the standarcd 10 basic questions with the usual scale. I did pretty well, and my confidence was actually built up.
I was happy to find out that several people left the class with a complete beginners homebrew kit. I am glad that the Green Growler had benefited from the class.
They have asked me to do another one next week, so I hope it is just as successful, as long as the weather holds out!
